Provide a synthesis of triphenylmethanol that uses a Grignard reaction and does not start with benzophenone.
A student decides to perform the synthesis of triphenylmethanol via the grignard reaction. She starts with 9.5g of bromobenzene (M.W. = 157) and uses 1.21g of Mg (M.W. = 24.3) and 9.1g of benzophenone (M.W. = 182). a. Calculate the limiting reagent. b. Calculate the theoretical yield of triphenylmethanol (M.W. = 260.3).
The synthesis of triphenylmethanol via the grignard reaction is given by the following equation (below): A student decides to perform the above reaction. She starts with 200 mg of bromobenzene (M.W. = 157) and uses 45 mg of Mg (M.W. = 24.3) and 0.36 g of benzophenone (M.W. = 182). a. Calculate the limiting reagent b. Calculate the theoretical yield of triphenylmethanol (M.W. = 260.3) c. She obtains 0.172 grams of of the product. What is her actual yield? d....
Triphenylmethanol can also be formed by the reaction of phenylmagnesium bromide with either benzophenone or diethyl carbonate. Give the mechanisms for both reactions and tell how many equivalents of the Grignard reagent would be needed.
What is the theoretical yield, pure % yield and crude % yield of Triphenylmethanol by Grignard reagent synthesis. 0.33 grams (0.22 mL) of bromobenzene is used (MW=157) with 0.068 grams of Magnesium (MW=24.32). 0.364 grams (MW=182.22) of benzophenone is used as well. 0.290 grams of Triphenylmethanol were obtained.
In an experiment we used, Grignard reagent reacted with benzophenone, in a two stepped process in order to create triphenylmethanol If you use excess Grignard reagent in this reaction, what contaminant would it yield after hydrolysis with HCl? Would you expect this contaminant to be removed in the extraction step?

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...
